Problems/Comments
The site is a former logging operations facility that ceased operation in 1994. Decommissioning activities are currently in the process, with an office, shop, three warehouses, and several above ground storage tanks, totes and drums for storage of petroleum products remaining at the site. On August 2, 2006 a Phase I was conducted that showed the following areas of concern: contaminated surface soils at the sort yard tank farm and Mt. Seley, a storage lot for used equipment and above ground storage tanks. On October 12 and 13, 2011 a Phase II was conducted that included further investigations of soils at the tank farm and the Mt. Seley storage area as well as observation of other petroleum storage activities that included a number of tanks, drums, batteries, scrap and unused materials, that included the following areas of concern: 1. Main Mill Yard and Tank Farm that includes two above ground storage tanks, a 10,000-gallon diesel and a 1,500-gallon unleaded gasoline tank. One 500-gallon diesel tank was removed in 2006. The Main Mill Yard stored several empty fuel storage tanks from 5,000- to 10,000-gallons and have been removed. Soil samples detected diesel-range organics (DRO) at 8,110 parts per million (ppm) at two feet below ground surface (bgs). 2. Mt. Seley was used for storage of heavy equipment and empty fuel tanks origniated from various logging camps, several trucks, heavy equipment and over 30 empty tanks with capacities of 500 to 1,000 gallons, as well as 20 tanks with capacities over 5,000 gallons. The majority of the equipment and tanks were removed with a few 55-gallon drums and propane tanks remaining. Soil samples detected DRO at concentrations ranging from 302 ppm to 3,470 ppm at 3 and 3.5 feet bgs. 3. Maintenance Shop Area included 25 lead acid batteries, a 500-gallon used oil storage tank, various tanks and drums, a lube oil tote and drum storage area includeing 40 totes and 29 drums, a 55-gallon drum that fuels a steam cleaner and various other servive equipment. No samples were taken in this area. 4. Evaporation Pond where surface runoff from the highway and runoff from the east end of the site where equipment had previously been washed down. Soil sample taken detected DRO at 185 ppm and residual range organics (RRO) at 563 ppm at the ground surface. 5. Former Office Tank that included an above ground storage tank that stored Jet-A fuel. Soil sample detected DRO at 404 ppm at one foot bgs. 6. Generator Tank and Mill Pod consiting of a 20,000-gallon double walled diesel tank that sits next to the mill pod. Soil samples detected DRO 1,420 ppm at one foot bgs. 7. Former Generator Building Tanks consisting of three steel single walled 500-gallon fuel tanks labeled used oil and diesel. Soil sample detected DRO at 51,300 ppm and RRO at 12,300 ppm at the surface. 8. Overhead Cranes consisting of an electronic crane and a hydraulic crane. Soil samples detected DRO at 36.2 ppm and RRO at 117 ppm. 9. Settling Pond and Oil-Water Separator - The facility is connected to a subsurface drainage system that flows into this lined settling pond that discharges to a 22,000-gallon oil-water separator. Soil samples detected DRO at 1,790 and 3,350 ppm and RRO at 7,540 and 15,600 ppm at 0.5 feet bgs. 10. Warehouses and Other Areas of Concern - The warehouse to the south of the maintenance shop was used for lube oil storage that included 23 totes containing hydraulic fluid, chain oil, turbine oil, six 5-gallon buckets filled with paints and lube-tubes and 25 drums of two-cycle and ISO32 chain oil. The warehouse to the south end of the yard stores radio and other electrical equipment, and the warehouse located on the north end of the mill is being relocated. The other areas of concern were surface staining and sheens on the ground throughout the site where vehicle maintenance, parking, or storage of petroleum products has occurred.

10/24/2013 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 79223 Main Mill Yard and Tank Farm. | Denise Elston |
1/27/2014 | Cleanup Complete Determination Issued | Cleanup at the site is complete; soil excavated from multiple areas across the site was bioremediated on site, has been sampled and meets site cleanup levels (ingestion pathway). It is now suitable for use as fill or cover onsite. 95UCL concentrations are less than 3500 mg/kg DRO and 3085 mg/kg for RRO. No groundwater pathway is present at this site as this facility was constructed on fill over tidelands. Migration pathway to surface water is incomplete due to dispersed and weathered nature of residual levels of petroleum and the distance of this soil from tidewater and surface water drainages. | Sally Schlichting |
